Comments about WEST System WEST System 207 Special Clear Hardener:
I like this product for exterior use under a varnish. In my own tests it at least doubles the life of the varnish.
Be aware that West is changing 207 from "Special Coating Hardener" to "Special Clear Hardener" under the same part number. The new product drops the Amber tint. Normally this isn't a big deal but if you are caught in the middle of a project and switch there can be a noticeable difference. It would be nice if West would have a tint additive if you wanted to continue using the Amber product (which is discontinued in production) much the same as Crystalac does with its warm dye toner, which changes the clear to traditional varnish tone.
